Our office building is currently being remodeled, including removing several walls. Last Monday, I noticed I was coughing a lot and had to blow my nose a lot. Tuesday, my throat was getting sore and the coughing was much worse. My supervisor sent me home early, fearing that dust might be worsening my asthma. I have been sick since then, with no sign that it is clearing up. I cough all night and when I try to lie down and rest during the day, the coughing gets much worse. Do you have any idea what I can do to help easy my symptoms?
